6 tpmtool - GnuTLS TPM tool
7
9 tpmtool [-flags] [-flag [value]] [--option-name[[=| ]value]]
10 All arguments must be options.
12
15 Program that allows handling cryptographic data from the TPM chip.
16
18 -d number, --debug=number
19 Enable debugging. This option takes an integer number as its
20 argument. The value of number is constrained to being:
21 in the range 0 through 9999
22 Specifies the debug level.
24 --infile=file
26 Input file.
27 --outfile=string
30 Output file.
31 --generate-rsa
34 Generate an RSA private-public key pair.
35 Generates an RSA private-public key pair in the TPM chip. The
37 key may be stored in filesystem and protected by a PIN, or
38 stored (registered) in the TPM chip flash.
39 --register
41 Any generated key will be registered in the TPM. This option
42 must appear in combination with the following options: generate-
43 rsa.
44 --signing
47 Any generated key will be a signing key. This option must
48 appear in combination with the following options: generate-rsa.
49 This option must not appear in combination with any of the fol‐
50 lowing options: legacy.
51 --legacy
54 Any generated key will be a legacy key. This option must appear
55 in combination with the following options: generate-rsa. This
56 option must not appear in combination with any of the following
57 options: signing.
58 --user Any registered key will be a user key. This option must appear
61 in combination with the following options: register. This
62 option must not appear in combination with any of the following
63 options: system.
64 The generated key will be stored in a user specific persistent
66 storage.
67 --system
69 Any registred key will be a system key. This option must appear
70 in combination with the following options: register. This
71 option must not appear in combination with any of the following
72 options: user.
73 The generated key will be stored in system persistent storage.
75 --pubkey=url
77 Prints the public key of the provided key.
78 --list Lists all stored keys in the TPM.
81 --delete=url
84 Delete the key identified by the given URL (UUID)..
85 --test-sign=url
88 Tests the signature operation of the provided object.
89 It can be used to test the correct operation of the signature
91 operation. This operation will sign and verify the signed data.
92 --sec-param=security parameter
94 Specify the security level [low, legacy, medium, high, ultra]..
95 This is alternative to the bits option. Note however that the
97 values allowed by the TPM chip are quantized and given values
98 may be rounded up.
99 --bits=number
101 Specify the number of bits for key generate. This option takes
102 an integer number as its argument.
103 --inder, --no-inder
106 Use the DER format for keys.. The no-inder form will disable
107 the option.
108 The input files will be assumed to be in the portable DER format
110 of TPM. The default format is a custom format used by various
111 TPM tools
112 --outder, --no-outder
114 Use DER format for output keys. The no-outder form will disable
115 the option.
116 The output will be in the TPM portable DER format.
118 -h, --help
120 Display usage information and exit.
121 -!, --more-help
123 Pass the extended usage information through a pager.
124 -v [{v|c|n --version [{v|c|n}]}]
126 Output version of program and exit. The default mode is `v', a
127 simple version. The `c' mode will print copyright information
128 and `n' will print the full copyright notice.
129
131 To generate a key that is to be stored in filesystem use:
132 $ tpmtool --generate-rsa --bits 2048 --outfile tpmkey.pem
133 To generate a key that is to be stored in TPM's flash use:
135 $ tpmtool --generate-rsa --bits 2048 --register --user
136 To get the public key of a TPM key use:
138 $ tpmtool --pubkey tpmkey:uuid=58ad734b-bde6-45c7-89d8-756a55ad1891;storage=user --outfile pubkey.pem
139 or if the key is stored in the filesystem:
141 $ tpmtool --pubkey tpmkey:file=tmpkey.pem --outfile pubkey.pem
142 To list all keys stored in TPM use:
144 $ tpmtool --list
145
147 One of the following exit values will be returned:
148 0 (EXIT_SUCCESS)
150 Successful program execution.
151 1 (EXIT_FAILURE)
153 The operation failed or the command syntax was not valid.
154 70 (EX_SOFTWARE)
156 libopts had an internal operational error. Please report it to
